Coined by Coleen McKechnie, this term is a shortened version of "let's do it."

The basic difference is that "let's do it" sounds like something a boring white man from the north would say. "Lezdewit" is a super-catchy, rolls-off-yer-tongue version that a hot, badass white girl from the south would say.

(The fact that said coiner is a le(z)bian in real life is merely coincidence and has nothing to dew with the spelling nor the word itself.)
